What these numbers mean
Fertility Rate
Fertile eggs ÷ total eggs set. Low fertility points first toward egg source, parent flock condition, storage, or timing before incubator settings.
Hatchability
Hatched chicks ÷ fertile eggs. This is the cleaner incubation signal. If it is low, review temperature stability, humidity pattern, turning, and lockdown handling.
Overall Hatch Rate
Hatched chicks ÷ total eggs set. This is the headline result, but it mixes fertility and incubation quality, so interpret it alongside the first two numbers.
